Twitter / Alex Payne: "The mood in our team meetings is directly proportional to the site's response times."
I.e., much better today! (Great work, Blaine, Alex, Britt, Jeremy.)
Note: It is not good luck to post about how you've solved your performance issues. So this is not that. There will surely be more.
Just a note to say: Phew! The mood's better around here today.
